:Solar_Analysis:
Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C9 event observed at
16/2357Z from Region 3825 (S16E20). There are currently 7 numbered
sunspot regions on the disk.
#
:Solar_Forecast:
Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one and two (18 Sep,
19 Sep) and expected to be low with a chance for M-class flares and a
slight chance for an X-class flare on day three (20 Sep).

:Geophysical_Activity:
Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at active to severe storm levels for the past 24 hours.
Solar wind speed reached a peak of 650 km/s at 17/0700Z. Total IMF
reached 19 nT at 17/0143Z. The maximum southward component of Bz reached
-18 nT at 17/0039Z.  Protons greater than 10 MeV at geosynchronous orbit
reached a peak level of 33 pfu at 17/1050Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 2394 pfu.

:Geophysical_Forecast:
Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (18 Sep), quiet to
unsettled levels on day two (19 Sep) and quiet levels on day three (20
Sep). Protons have a chance of crossing threshold on day one (18 Sep)
and have a slight chance of crossing threshold on days two and three (19
Sep, 20 Sep).
